CompTIA Security Plus Mock Test Q403

A network administrator has purchased two devices that will act as failovers for each other. Which of the following concepts does this BEST illustrate?

A. AuthenticationB. IntegrityC. ConfidentialityD. Availability

Correct Answer: DSection: Compliance and Operational Security

Explanation:
Failover refers to the process of reconstructing a system or switching over to other systems when a failure is detected. In the case of a server, the server switches to a redundant server when a fault is detected. This strategy allows service to continue uninterrupted until the primary server can be restored. In the case of a network, this means processing switches to another network path in the event of a network failure in the primary path. This means availability.

Incorrect Answers:
A: Authentication is used to verify that a person who sent the message is actually who they say they are.
B: Integrity means that data cannot be tampered with or altered without detection.
C: Confidentiality means that data retains its privacy.
